something went wrong with last commit? =)

Last working version for me docker pull qmcgaw/gluetun:v3.27.0

ghost commented 2 years ago

Same error after upgrading to version 3.28.0 from 3.27.0 Host: Ubuntu 20.04 Arch: amd64 Running with docker-compose

qdm12 commented 2 years ago

What a Sunday morning wake up! šŸ˜„

It looks like I have some CI tagging/pushing spaghetti mix-up, pr-848 is from https://github.com/qdm12/gluetun/pull/848

Anyway I manually pushed the latest image so it works again, and will fix up the build pipeline.

Let's leave this opened until I fix the build pipeline. Anyway I need to rework it to do another release tag like today šŸ‘

qdm12 commented 2 years ago

Build pipeline fixed! šŸ‘ You can also now use image :v3 which corresponds to the latest v3 release, if you prefer stability over the edge.

egadgetboy commented 7 months ago

Update (Resolution): Well, that's strange... but I updated my Compose from image: qmcgaw/gluetun:latest to image: qmcgaw/gluetun:v3.37.0 and the Gluetun container is healthy now

Why would this same issue from 2022 suddenly affect me? "panic: runtime error: invalid memory address or nil pointer dereference"

I've been running the latest version (v3.37.0) for several months and everything was fine. But it broke today. I tried removing the container and setting it up again, but the same error results.

Ubuntu Server 22.04.4 with latest updates/upgrades VPN: Proton Docker Compose

ritesh-kanchi commented 7 months ago

@egadgetboy Funny enough, ran into the same problem just now - thank you for recommending to use v3.37.0....don't know why we were getting those problems...

JackPo commented 7 months ago

Running into the same problem now also... wth?

JackPo commented 7 months ago

yea.. for some reason, what egadgetboy suggested works, updated compose with specific version and it worked.

cmorebutz commented 7 months ago

Ditto... latest update causes issue #855. Rollback to v3.37.0 fixed.

egadgetboy commented 7 months ago

Since v3.37.0 is the latest release, not sure if this is the issue (as in... which version is being pulled when using :latest) but I noticed that this page shows the latest version is an older version 3.35.0: https://github.com/qdm12/gluetun-wiki

steveb166 commented 7 months ago

Same issue occurred here, fixed with changing the tag to v3.37 in compose.

NewFangled1 commented 7 months ago

Ugh, had the same issue today. Due to the fact that I added another container to my docker-compose file, I assumed I had corrupted something that way. Now it seems more likely that it pulled the latest gluetun at the same time and caused the error. Specifying v3.37.0 fixed the issue.

captainkev76 commented 7 months ago

Same thing here. Thanks for the workaround. Must remember to switch back at some point in future :-)

qdm12 commented 7 months ago

To the many people who commented today, please note this issue is completely irrelevant to #2169 - it's just the panic: runtime error: invalid memory address or nil pointer dereference message which is the same, but this is a Go (programming language) builtin common error, when trying to access a nil pointer.
